Excluding the $Windows.~BT and other protected folders from backups to avoid errors
There are certain folders which cannot be included in your file backup including the folder where the DR Boot Disc media is built, if the Advanced method was utilized . This folder name is "C:\ProgramData\TempDR"; if it appears in your file backup error logs will need to be excluded from your file backups since that is a PROTECTED FOLDER which will deny access to back up files within it.
The easiest and most thorough method to use to exclude that folder from being selected for backup is to edit the "Default Exclude Filter" setting. Utilizing this method for exclusion will save you the time and hassle of editing each file backup job to exclude that folder from NovaBACKUP.
To make this change to exclude that folder you will load NovaBACKUP and click on the large circle NovaStor logo button at the top left of the application, then go to Default Settings -> Advanced Options -> click on "Edit default exclude filter" -> The notepad program will open up with a text file "nsexc.ini" (this file is physically located in the "C:\ProgramData\NovaStor\NovaStor NovaBACKUP\Profiles\" folder), simply change the line under [exclude] from path.numberOfItems=13 to 14 and then add this line at the bottom as "path.item.13=?:\ProgramData\TempDR".
Follow the example below for how your "nexc.ini" text file should look.
The example would look like this, you will be making two changes:
[exclude]
path.numberOfItems=14
path.item.0=%systemdrive%\win386.swp
path.item.1=%systemdrive%\pagefile.sys
path.item.2=%systemdrive%\hiberfil.sys
path.item.3=%systemroot%\debug
path.item.4=%systemroot%\prefetch
path.item.5=%systemroot%\temp
path.item.6=?:\recycler
path.item.7=?:\recycled
path.item.8=?:\$Recycle.Bin
path.item.9=?:\$RECYCLED
path.item.10=*\ntuser.dat.log
path.item.11=*\usrclass.dat.log
path.item.12=?:\System Volume Information
path.item.13=?:\ProgramData\TempDR
Once done editing the file you will save it by clicking File menu and then Save and then exit notepad, or you can simply try closing the text file and it will prompt you to save if you have not. Then click OK at the bottom of the screen in NovaBACKUP's Advanced Options screen.
Next, exit out of NovaBACKUP; if you do not exit out of NovaBACKUP at least once after making this Default Exclusions change then it won't show the affect visually.
This method will affect ALL of your file backup jobs without you editing them to exclude and never attempt to back up the ProgramData\TempDR folder.
You could also make additional exclusions if you need to such as adding the "?:\Windows.old" folder to be excluded or any other paths you wish to add. Make sure to increment the "path.numberOfItems" variable at the same time if you do add additional paths in to exclude.
